Description

The present invention relates to a system for the localization of extinguishing agent extraction points according to the preamble of claim 1.

Are known systems for the localization of extinguishing agent tapping points in the form of signage of, for example, hydrants on roads, sidewalks, etc., in combination with directories in which the position of extinguishing agent tapping points is entered and the example. Are carried in a fire department of a fire department to a site can. Such known systems are in emergencies, especially in fires, accidents and the like, the fastest possible localization or location of extinguishing agent sampling points and can in addition to natural extinguishing agent withdrawal points, such as standing and flowing waters, and artificial extinguishing agent extraction points or facilities, such as. Hydrants Water removal, storage tanks with water or other extinguishing agent or the like include. Despite numerous efforts, the location detection of extinguishing agent tapping points is still often complicated by practical circumstances, for example. By adverse weather conditions, coarse contamination such as foliage and soil, damage or the loss of signage and / or parked cars. Also, for example, are needed for water extraction hydrants usually integrated in sidewalks, squares or streets. In rural areas, however, these can also be off the beaten track. Existing signage is often attached to masts parallel to the road and therefore hardly visible at first glance. Often a small group of firefighters has the first Task, with the help of often obsolete directories suitable extinguishing agent, especially water supply points to locate. Only then can it be started, for example, to install a hydrant or the like in the water supply, for example, for firefighting.

A system according to the preamble of claim 1 is known in the art US 2009/0043462 A1 known. Out US Pat. No. 7,099,781 B1 is a portable hydrant meter and a system known for its use.

Against this background, the invention has the object of developing a system for localization of extinguishing agent removal points advantageous, so that in particular the aforementioned disadvantages can be avoided as much as possible.

The object is achieved according to the invention in conjunction with the characterizing features of claim 1. This makes it possible, by means of the first radio signal (call or activation signal) in the vicinity of the place of use located extinguishing agent withdrawal points for transmitting respective so-called. Second radio signals (response signals) (ie to "activate", these second and possibly further from the extinguishing agent tapping points emitted radio signals may contain information suitable for localization and in particular for the selection of a suitable water supply point, which may be received by the mobile localization device and used by a person, possibly after intermediate data processing. As explained below, different extinguishing agent tapping points can use their respective specific information or their specific information associated therewith, such as, in particular, their current positional or positional coordinates, their instantaneous power (in particular maximum flow rate, stored quantity of extinguishing agent, etc.). and / or, for example, concerning the type of sampling point (ie, for example, hydrant, tank, fire extinguishing riser of buildings, water bodies or the like). The system according to the invention is thus suitable for the rapid and exact localization of extinguishing agent removal points, for example of hydrants, and may also be referred to as a water-searching system (WFS or Water Finding System) with regard to the preferred use in water withdrawal points. Since saving time very often decides on life and death in rescue operations, the advantages of wireless technology are here, which makes a complex optical search unnecessary and reduces the costs for additional fire hydrant signage or even makes it superfluous. With the system according to the invention, for example, hydrants or other water tapping points can be found right away, so that unnecessary, time-consuming ways are spared. Also in the course of reorganizations and mergers of fire departments a uniform system for hydrant localization becomes more and more interesting. The invention makes it possible, in an innovative application, for the wireless system to be used for the meter-accurate location of a plurality of immovable objects (here water supply points, such as, for example, hydrants) and with the aid of a moving object (in particular a mobile display device). In addition, the system according to the invention proves to be useful and helpful, since it depending on the design without the well-known positioning system GPS (= Global Positioning System = Global Positioning System) is functioning as a practically world-wide, satellite-based navigation system. In this respect, there are advantages when using the system according to the invention in tunnels, areas without satellite reception or in closed rooms without suitable GPS reception. The system according to the invention can serve in particular for the localization of extinguishing agent removal devices, such as, for example, hydrants for the removal of water. The system according to the invention can either immediately contain a number of extinguishing agent removal points, in particular extinguishing agent removal devices such as, for example, hydrants, or serve as a system for correspondingly equipping existing extinguishing agent removal points. For the preferred development, there is the possibility that in each case a localization module is attached to at least one or more hydrants. There is also the possibility that the localization module has radio wave receiving means coupled to one another as well as signal content providing means and radio wave output means. It is preferred that the second radio signal is provided with respect to its signal content from the signal content providing means.

It is preferably provided that the mobile localization device is arranged fixedly or detachably in a vehicle, such as an emergency vehicle of a fire brigade, and is preferably portable by a person due to its low weight, while having its own energy supply device (eg batteries, rechargeable batteries or the like) is. It is possible for the transmission of the abovementioned first radio signal, which can also be referred to as a call or activation signal with regard to its function or significance, at least one radio transmitter to the mobile localization device and / or in a vehicle fixedly and / or loosely and / or in one Building is fixed or loose. Accordingly, a plurality of such radio transmitters can be provided for transmitting the so-called first radio signal, ie of radio signals of this first type or content. Preferably, ie not necessary, the mobile localization device may have a radio receiver suitable for receiving GPS radio signals and suitable data processing means for determining its own position by means of the GPS signals. Alternatively, the mobile localization device can determine its own position by means of radio cell location.

It is preferably provided that, emitted by a particular localization module, preferably emitted, radio signals this specific localization module specifically associated information, this information In turn, it may be specifically tuned to a particular extinguishing agent withdrawal point (or, for example, to a particular type of extinguishing agent withdrawal point) at which the localization module is or is to be located, or that is associated with the localization module. In this respect, the information contained in the radio signals may preferably be information concerning the position or the coordinates (for example GPS coordinates) of the extinguishing agent removal point and / or the type of extinguishing agent removal point and / or the available removal capacity or capacity of the extinguishing agent removal point and / or a label (eg identification number or identification number) of the extinguishing agent tapping point act. This proves to be particularly advantageous if the system according to the invention with respect to various types of water supply points, such as Löschmittelsteigleitungen in buildings, swimming pools, fire ponds or ideal sampling points on streams and rivers is extended to ensure a nationwide supply of the indispensable extinguishing agent. Also proves to be practical, in the course of radio positioning of, for example, hydrants together with the radio signal for localization on a specific identifier the mobile, preferably cartographic display system not only to indicate the position, but also the nature and capacity of the water tap. If, for example, a hydrant changes as a result of construction measures to a position change, its signal content providing means can be adapted to its changed or new location coordinates, for example by reprogramming or by replacing the localization module. The mobile localization device may comprise display means for displaying the position of the localization device and the respective position of one or more extinguishing agent removal points, for example a multifunctional display. There is the possibility that the display can, for example, map various water supply points in a cartographic manner, even without reference to a GPS map. By means of a display provided on the localization device, the possibility can also be created, in addition to position coordinates from localized extinguishing agent taps also continue to represent this associated information, such as, for example, the type, in particular currently, available withdrawal capacity or capacity, a label or the like. Also, the localization device can be further developed in such a way that, for example, in high-rise buildings, all functional connections of the built-in extinguishing agent riser or built-in extinguishing agent risers can be identified in stages and displayed spatially. Also in this case it is preferred that the type (in particular dry or wet riser), momentary capacity and identification number can be recognized on the display. For this purpose, localization modules which are adapted to a transmission of signals with corresponding information content can be arranged at said connections of the extinguishant riser lines. In a comparable manner, practically any other types of extinguishing agent removal points can also be integrated into the system according to the invention, for example swimming pools and / or other (also) private extinguishing agent removal points, which, for example, can also lie on different levels in buildings. In this case, it is preferred that the localization device is also adapted or suitable for displaying such water tapping points, in particular also at different levels. Alternatively or in combination, information reproducing means for optical and / or acoustic reproduction of localization signals may be present. This proves to be expedient in particular in connection with the fact that the mobile localization device has data processing means which are suitable for determining the distance and / or the directions from the own instantaneous position of the mobile localization device to the respective positions or coordinates of different extinguishing agent removal points. For example, by means of the frequency of a light or sound signal in which this occurs per unit time, the changing distance from the extinguishing agent withdrawal point are displayed. Alternatively or in combination with, for example, light or sound signals, the data processing means determined distance and / or directions from the position of the localization device to the positions of the extinguishing agent tapping points, in particular cartographically, are displayed by means of a display of the localization device. In order that emergency vehicles can be navigated more quickly to the respective deployment site, it is possible for the emergency services to be in direct contact with the deployment control center by means of the localization facility, which in this case can also serve as a navigation device. It is possible that the emergency services at the start of the action by the operations control center, the task forces are also sent via radio technology directly to the localization device, so that the previously manual input in the vehicle is eliminated. After that, the route calculation can automatically follow, which also ensures the fast driving eg. A road in the right place (even with the same name streets in different places). At the place of use, by means of a display of the localization device, the current own position of the localization device and the respective positions of one or more extinguishing agent withdrawal points can be displayed and in particular (possibly cartographically) the route descriptions determined by the data processing means of the mobile localization device to one or more extinguishing agent removal points. According to the invention, the mobile localization device has data processing means which, preferably on the basis of predetermined (for example, programmed) criteria, for determining or selecting a preferred extinguishing agent removal point taking into account the respective distances and / or the respective route descriptions and / or the respective type and / or the respective available capacity (s) of a plurality of extinguishing agent tapping points. It would be conceivable here, for example, a situation in which, based on the current Position of the mobile localization device, the nearest extinguishing agent removal point is a hydrant with low extinguishing performance and only a slightly greater distance one with a localization module provided with a water supply point of a river. The localization device can here, possibly also depending on a selected default, weight the different extinguishing performance of the two water tapping points more than their slightly different distance and mark the flow as the preferred water tapping point by means of their information reproducing means. Likewise, for example, there would also be the possibility that the mobile localization device would make a preferred choice between a plurality of artificial extinguishing agent removal points or devices, such as, for example, hydrants. Preferably, for the documentation and control of care, maintenance, repair and use each sampling point also provided with the already mentioned identification number. This also facilitates the computer-aided creation or evaluation of operational or repair statistics in the operations center, for example for special fields of use.

For the radio location, the mobile localization device and / or the localization modules can preferably each have an antenna. In a first preferred embodiment of the localization module it is provided that the radio wave receiving means are designed as radio receivers, that the signal content providing means comprise data processing means (eg a computer) and / or a data memory and that the radio wave output means are designed as radio transmitters. In this case, the so-called first radio signal (call signal) received by the radio receiver can be processed in the computer and the computer, if necessary also depending on the content of the first radio signal, by means of its data memory, cause the radio transmitter to send the so-called second radio signal to the latter Extinguishing Media Center contains specific information. In an alternative embodiment of the localization module, the radio wave receiving means, possibly signal content providing means and the radio wave output means of the localization module can be implemented as a radio reflection module, ie the principle of radio wave reflection known to a person skilled in the art can be used come. In this case, the mobile localization device first sends the so-called first radio signal to, for example, a plurality of hydrants, each of which responds by radio wave reflection. In contrast to the first exemplary embodiment, in which the first radio signal is actively answered with the second radio signal, a passive answer takes place during the radio wave reflection. While in the first exemplary embodiment there is the possibility that the so-called first radio signal, for example, must first enable a power supply (eg battery) of the localization module, in the second exemplary embodiment (radio wave reflection), depending on the design, it may even be entirely dependent on an energy supply of the localization module be waived. There are two ways to use. On the one hand, the so-called first radio signal can be reflected by the localization module substantially unchanged as a so-called second radio signal (ie, in this case, the signal content providing means cause a virtually unchanged acceptance of the first radio signal as the second radio signal). The mobile localization device can determine the distance between its own position and the position of the extinguishing agent removal point on the basis of the time interval from the sending of the first radio signal to the reception of the second radio signal, ie on the basis of the transit time determination. Alternatively, the first radio signal can be modulated or changed on impinging and / or leaving its radio waves on the localization module and thereby the so-called second radio signal can be generated, which is passively sent back to the mobile localization device. The modulated second radio signal may, for example, include information about the position or coordinates, about the available erasing power or capacity, about the type etc. of the extinguishing agent tapping point. In the first and second embodiments, there is the possibility that the first radio signal is transmitted by a radio transmitter installed in the mobile localization device, preferably only after reaching the place of use. Alternatively or in combination, one or more radio transmitters for transmitting the radio signals of the first type ("first radio signals") independently of the mobile localization device be present. For example. Such a radio transmitter may also be located on a service or fire vehicle or in a building (eg control center).

It is possible for the first predetermined radio signal to switch the localization module from a rest or stand-by mode, preferably for a predetermined limited period of time, into an operating state during which the second radio signal is emitted. Within the activation period, the second radio signal can be emitted once or more frequently, for example continuously, quasi-continuously or in comparatively larger time intervals. A localization module may be executed, for example programmed, in such a way that it automatically switches back to sleep mode after this period of time.

It is structurally possible for the localization module to be integrated in the housing of a hydrant, for example an underfloor hydrant. For example, the localization module can be completely or partially integrated into a hollow body protected against corrosion, for example into a thick hollow screw or the like, and this hollow body can be fastened in or on, for example, a hydrant. It is also possible to integrate the antenna and energy source of the localization module into the hollow body. Depending on the embodiment transmitter and receiver or a module according to the reflector principle can be integrated into the hollow body.

The Lokalisationsmodul is, regardless of an optional configuration as a transmitter / receiver module or as a reflector module, preferably mounted in the hydrant body in association with a hydrant, in the case of a different type of water tap nearby. The radio-frequency reflection module (or radio-frequency reflector) can remain in stand-by mode until it is hit by an external radio signal. In this case activated itself the module itself and sends the hydrant data with a, preferably amplified, echo back to the transmitter or display device. This or the mobile localization device is able to quickly calculate the exact position of the water sampling point from the received data and display the position by means of visual representation on the display and possibly with acoustic signaling.

The localization module may include evaluation or signal processing means adapted to evaluate the first predetermined radio signal for the presence of predetermined, preferably one or more specific localization modules for distinguishing other localization modules, so that the evaluation means only locates the localization module to convert this matching information from the standby or sleep state into the operating state. Depending on local conditions, the system according to the invention may comprise, as extinguishing agent removal points, preferably a number of hydrants and / or at least one extinguishing pond and / or at least one flowing water, for example a stream or river.

An expedient development is seen in that the system comprises at least one extinguishing agent sampling site data storage, which for several extinguishing agent tapping points this specifically assigned extinguishing agent sampling point data, preferably concerning the respective coordinates and / or the type and / or the currently available withdrawal capacity or capacity and / or a Identification of the respective extinguishing agent withdrawal points, wherein the extinguishing agent withdrawal point data storage can be located in the mobile localization device or run separately and connected to a radio transmitter for radio transmission of extinguishing agent withdrawal point data to the mobile localization device. In this case it may be sufficient that the localization modules of the Extinguishing agent tapping points only transmit their specific identifier by means of the second radio signal to the mobile localization device. However, the possibility also, for example, to transfer the extinguishing performance of the respective extinguishing agent tapping points or of their localization module by a second radio signal, the advantage that then at sampling points whose extinguishing power can change over time (eg. The storage volume in a tank) also of the localization modules can be queried by means of appropriate sensors connected to each current extinguishing ability and then transmitted after activation by radio signal. It is also possible that by means of the mobile localization device on the way by radio extinguishing agent removal point data are retrieved from the extinguishing agent withdrawal point data store, preferably targeted for the environment of a particular site. There is also the possibility that the extinguishing agent collection data storage is equipped with a comprehensive list of all European hazardous materials warning panels. A corresponding large data memory may be integrated into the localization device and / or be spatially separate therefrom (for example, in a deployment control center). It is preferred that the data memory, in particular the mobile localization device, can submit at least one suitable extinguishing agent proposal in addition to each hazardous substance. If the extinguishing pickup location data memory is spatially separate from the mobile location device, there is a possibility that an operator of the localization device enters therein, for example by means of a keyboard, a name for a standardized hazardous materials warning board found at a location and transmits by radio to the remote extinguishing center location data store; in order to receive an extinguishing agent proposal by radio. If the data memory is located within the localization device, after the designation has been entered, the extinguishing agent proposal can be obtained directly therefrom. In addition, potential hazards and / or dangerous goods and / or places associated with the topographic map should be considered the region can be displayed both visually and acoustically. The system according to the invention is not limited to specific frequencies or network areas. Rather, it is preferred that the system can utilize all frequencies / network areas, such as preferably GSM / ISM and the like. According to a further aspect, the preferred development provides the possibility that the hydrant has a heating device which can be remotely activated by means of a radio transmitter when selecting the hydrant, in particular by means of the mobile localization device. This allows further time savings as manual defrost on site becomes redundant.

The invention additionally relates to a method for the localization of extinguishing agent removal points, preferably for the localization of extinguishing agent removal device such as hydrants for water extraction, and proposes for advantageous embodiment, that a system for the localization of extinguishing agent extraction points according to one or more of claims 1 to 14 is used ,

Fig. 2

schematically simplifies another example of application of the method according to the invention.

Fig. 1 shows the system 1 according to the invention for the localization of different, here exemplified for the representation of extinguishing agent tapping points 2 according to a first preferred embodiment, or shows preferred components of a system according to the invention 1. It is understood that the illustrated system 1 just in terms of in The description explained expandability by other components, in particular by additional and / or other extinguishing agent removal points would complement. The same applies to Fig. 2 , Likewise, the size ratios and distances between the system components are not reproduced in scale or scale in both figures. It shows Fig.1 compared to Fig. 2 more details of the system, while in the presentation of Fig. 2 the overall situation is in the foreground.

At the two in Fig. 1 The extinguishing agent removal points 2 shown are each a hydrant 3, which is equipped with a conventional connection 4 for the removal of water. The system includes a mobile localization device 5, which is portable by means of handles 6 by a person. The localization device 5 has in its interior, therefore indicated by dashed lines, a radio transmitter 7. This is used to send a so-called. First, predetermined in its information content radio signal 8 in different directions, the radio signal 8 (as well as further emitted in multiple directions radio signals) simplistic only shown as a radio link line to a receiver. In the example shown, the first radio signal 8 reaches from the mobile current first position P _{1 of} the mobile localization device 5, the two hydrants 3, which are located at different distances from P ₁ to the respective stationary positions P ₂ and P ₃ . The so-called first radio signal 8 arrives there at a respective localization module 9, which is fixedly connected to the hydrant 3, to a radio wave receiving means 10, which in the example is a radio receiver 11. The radio wave receiving means 10 are in communication with signal content providing means 12, which in the example is an electronic circuit 13 with a memory. This causes associated radio wave delivery means 14, which is a radio transmitter 15, to emit a so-called second radio signal 16 or 16 '(depending on the hydrant 3), which in turn is received by a radio receiver 17 in the mobile localization device 5 , For a better overview are in Fig.1 the radio signals 8, 16 'of the hydrant at P ₃ shown in phantom. The two so-called second radio signals 16, 16 ', ie the two response signals, differ in their content from the so-called first radio signal 8 which corresponds to both hydrants 3, ie call or activation radio signal. The second radio signals 16, 16 'contain in the selected example information about the respective positions P ₂ and P ₃ (or the associated coordinates), about the type of water sampling point and about their water capacity. Since the two hydrants are identical in construction in the example, the two second radio signals 16 or 16 'emitted by them differ only with respect to the coordinates (locations) transmitted therewith. To indicate this symbolically, different reference numerals 16 and 16 'were chosen. Schematically, it is indicated that each localization module 9 has its own energy supply device 18. The radio receiver 17 receives both so-called second radio signals 16, 16 'or response signals, which may also have different distinctions to distinguish them, and forwards them to signal processing means 19 and information reproduction means 20 of the mobile localization device 5. The signal processing means allow the separate evaluation of the second radio signals 16, 16 'with respect to the therein respectively contained information. The localization device 5 has operating means 21 with a keyboard, by means of which operating parameters desired for the localization and selection of extinguishing agent removal points 2 can be set. The information reproducing means 20 include a cartographic display means 22 or multi-functional display, on which can be displayed in an overlaid land or road map detail of the signal processing means determined positions P ₁ , P ₂ and P ₃ together. The information required for the determination of the own position P ₁ is obtained from a radio receiver 23 integrated in the mobile localization device 5, which receives GPS signals 24 from several GPS satellites 25 (of which in FIG Fig. 1 only one satellite 25 is shown) and also connected to the signal processing means 19. The determination of the own position P ₁ can be carried out alternatively or in combination with the described GPS location by means of radio cell location. In the example, the position P ₁ is located at a place of use, for example near a burning house or object. On the basis of the position display on the screen, the operator carrying the mobile localization device 5 can clearly see that there are two similar hydrants 3, but located at different distances from the point of use P ₁ . On the basis of this, the operator can decide on the closer hydrant 3 located at position P ₂ (or also leave this decision to the signal processing means 19 in a selectable automatic mode). If the hydrant 3 at position P _2, for example. By means of the operating means 21 is selected (for example. Marked with a cursor), the distance between the variable position P ₁ and the fixed position P ₂ , which changes upon movement of the operator, by accordingly variable signals of a flashing light 26 or a speaker 27 are displayed. In turn, the data processing means 19 can serve to generate these light or sound signals.

In the Fig. 1 shown mobile localization device 5 can be worn as required by an operator or, for example. Loosely or permanently installed in a vehicle (in Fig. 1 not shown) and, as described, makes it possible to activate and locate the localization modules 9 of the water tapping points 2, preferably by radio technology, upon arrival at the place of use. By means of this bearing by a display device, the type and capacity as well as the coordinates of the water extraction point (hydrant 3) can be determined as a result of the identification data transmitted by the respective localization module 9 of the water extraction point 2. On the basis of the hydrants 3 received, mutually different response signals can be easily and accurately locate a suitable for the use of water supply point. In Fig. 1 is designated by the reference numeral 28, the building of a fire department control center. This is (schematically indicated) another radio transmitter, which is also denoted by the reference numeral 7. Also by means of this so-called first radio signals 8 for activating the localization modules 9 of extinguishing agent tapping points 2 can be emitted. If required, the radio signals 8 can also contain an identifier by means of which, for example, only certain types or only water tapping points 2 present in a desired local area are activated. By means of the radio transmitter 7 of the control center, localization modules 9 can be activated not only during use but, for example, during an exercise by radio from their otherwise existing sleep mode. In the example, the information reproducing means 20 of the localizer 5 below the cartographic display 22 comprise a display window 31 with display fields 32 for the respective GPS coordinates of the positions P ₁ , P ₂ and P ₃ and display fields 33 for the display of the respective type and performance of the extinguishing media outlet.

In the in Fig. 1 In the embodiment shown, the system 1 has an extinguishing agent withdrawal point data storage 34 which is exemplary in the building 28 of the control center is housed. This contains data from a large number of extinguishing agent outlets. As indicated schematically, this memory is connected to the stationary radio transmitter 7. The radio transmitter 7 can transmit a radio signal 35 to the radio receiver 17 of the mobile localization device 5 in order to transmit to the mobile localization device 5 extinguishing agent removal point data (for example of type and performance) which can relate to different extinguishing agent removal points. As an alternative or in combination with the extinguishing agent removal point data storage 34 accommodated in the control center, the mobile localization device 5 itself can have such an extinguishing agent removal point data storage 34, which, for example, is connected directly to the data processing means 19. This is in Fig. 1 also indicated schematically.

Fig. 2 shows schematically simplified another embodiment of the system 1 according to the invention or another preferred method example. In it are for a better overview of Fig. 1 corresponding components and features provided with the same reference numerals. To Fig.1 In addition, an operator 29, which carries a mobile localization device 5 from a vehicle 30 of a fire brigade to a deployment site 36, and as a further extinguishing agent removal point, an extinguishing pond 37 is shown. Again, the various radio signals explained are simplified with arrows. By means of the radio signal 35 emitted from the building 28 of the control center, it is additionally possible, for example, to transmit deployment location data to the mobile localization facility. Another identical localization device 5 has remained in the vehicle 30. In the building 28, a further localization device 5 similar in terms of construction and function, however, may be present for stationary use, by means of which the so-called second radio signals 16, 16 'emitted by the localization modules 9 can also be received. Incidentally, the structure and the method of operation or method are as to Fig.1 described.
